Abstract
The tensile failure in micromachined aluminium thin films by grain thinning was investigated. The microtensile tests showed that the mechanical characteristics of the free-standing beams were different from those of the bulk material. It was found that the strain softening and low ductility prevail in free-standing thin films because of the absence of neighboring grains in the thickness direction.
